Answer:
c = 27.9
B = 62.13°
C = 89.90°
Step-by-step explanation:
We are given the following values:
A= 121.59°, a = 27.9 cm, b = 52.6 cm
a) Finding side c
We would use Pythagoras Theorem
c² = a² + b²
c = √(a² + b²)
c = √(27.9² + 52.6²)
c = 59.54cm
≈ Approximately = 59.5cm
b) Finding B
We would be using Cosine rule to find Angle B
Cos B = a² + b² - c²/2ab
B = arc cos ( a² + c² - b²/2ac)
B = arc cos( 27.9² + 59.5² - 52.6²/ 2 × 27.9 × 59.5)
B = 62.13268°
B = 62.13°
c) Finding C
We would be using Cosine rule to find Angle C
Cos C = a² + b² - c²/2ab
C = arc cos ( a² + b² - c²/2ab)
C = arc cos( 27.9² + 52.6² - 59.5²/ 2 × 27.9 × 52.6)
C = 89.9°
To solve this problem you can apply the following rule of three:
$ 1,435 ---> 100%
$ 1,595 ---> x
Clearing x we have:
x = ((1595) / (1435)) * (100)
x = 111.1498258
Then, the difference is:
111.1498258 - 100 = 11.14982578%
hundredths of a percent:
11.15%
Answer:
the dealer's price from the Blue Book: It is 11.15%
<span> Add x to both lenght and width and you get 25+x and 10+x. Set up equation with new area </span>
<span>(25+X)(10+X)=1000 </span>
<span>solve using quadratic formula

Answer: 36.84
(lmk if this isnt right)
Step-by-step explanation:
To find the perimeter of the rectangle:
3+3+3+3+3+3=18
or
3(6)=18
To find the diameter of the circle:
12-(3+3)
12-6=6
You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.
C=πd
Substitute
C=3.14(6)
Multiply
C=18.84
Add the perimeter of the rectangle and the circumference of the circle.
18+18.84=36.84
